Cher has contributed her vocal talents to two tracks on the new Wu-Tang Clan album.

Just in case that didn’t register first time: Cher is on the new Wu-Tang Clan album.

[Cher: ‘Wu-Tang, baby. They rock the world’]

Sinking in yet?

Earlier this year we reported on the fact that the Staten Island crew are releasing just one copy of their new album Once Upon A Time In Shaolin, which will be encased inside an engraved silver-and-nickel box, then taken on a tour around museums, art galleries, and festivals. After which it is expected to fetch millions.

But in an even more bizarre twist, the hip-hop collective revealed on their website that Cher, using her pseudonym ‘Bonnie Jo Mason’, which she used in 1964 when she released her first solo single, ‘Ringo, I Love You’, is one of guests on the ridiculously exclusive LP.

The 67-year-old singer reportedly recorded her parts separately, and there was no “direct interaction”.

You can hear a short excerpt of Cher’s contribution in a video from Forbes, where she sings: “Wu-Tang, baby. They rock the world.”

Is this the most unlikely musical collaboration of all time? Probably, but here are six more contenders.
